- [x] Warning: The command '/usr/bin/lwp-request' has been replaced by a script: /usr/bin/lwp-request: Perl script text executable

-> Reply: it is better to disable the RootLogin from ssh (Already updated at the ssh_config file) -> https://unix.stackexchange.com/questions/534476/rkhunter-giving-ssh-root-login-warning-even-when-both-config-files-are-set-to-n/534757#comment990622_534476

- [x] Warning: The SSH configuration option 'PermitRootLogin' has not been set.
The default value may be 'yes', to allow root access.

-> Reply: it seems like a common warning, ubuntu seems to e using Perl scripts in stead of strings, thus `rkhunter` raises that warning as they are easy to manupulate | it also seems to disapear if we set up the OS's PKG_MNG to DPKG (default for Debian/Ubuntu) https://forums.linuxmint.com/viewtopic.php?p=1296001&sid=162713fdca27651bb48aca140e297e99#p1296001

- [X] Warning: Suspicious file types found in /dev:
/dev/shm/PostgreSQL.27108374: data

-> Reply: it looks legit to have Database files (owned by the database user in /dev/shm) https://www.linux.org/threads/rkhunter-showing-warnings.30519/ thus, there seems to be no problem with that
